Yes, most of the aviation onboard Soviet icebreakers came from the Polar aviation branch of Aeroflot, whit rather stricking high-visibility markings. Of what Ive been observing, only Ka-32 has been other onboard helicopter on hangar capable icebreakers aside the Mi-2, never seen pic of older piston engined Kamovs, and naturally the Big Mi-8 (though visiting the biggest flight decks) seems to have been too crambed for the hangars.
Anyways, I can propably now kindly resign from all by preservations of the remaining ice-breakers I've claimed, since I doupt I can match Lazer's skill and determination in these field, and It would be nice to see more of them
